% ' UNIX Tarball creator ' ==================== ' Author: Chris Read ' Version: 1.0.1 ' ==================== ' ' This class provides the ability to archive multiple files together into a single ' distributable file called a tarball (The TAR actually stands for Tape ARchive). ' These are common UNIX files which contain uncompressed data. ' ' So what is this useful for? Well, it allows you to effectively combine multiple ' files into a single file for downloading. The TAR files are readable and extractable ' by a wide variety of tools, including the very widely distributed WinZip. ' ' This script can include two types of data in each archive, file data read from a disk, ' and also things direct from memory, like from a string. The archives support files in ' a binary structure, so you can store executable files if you need to, or just store ' text. ' ' This class was developed to assist me with a few projects and has grown with every ' implementation. Currently I use this class to tarball XML data for archival purposes ' which allows me to grab 100's of dynamically created XML files in a single download. ' ' There are a small number of properties and methods, which are outlined in the ' accompanying documentation. ' Class Tarball Public TarFilename ' Resultant tarball filename
